Car cd player help?

Hi, i have a wharfedale car cd player i had to change the battery and the starting motor. And guess what i cant remember how to reset the cd player i know its two buttons but which two ???//??Car cd player help?You would have reset it when you changed the battery. Why would you need to reset it.. these units don`t have security codes either.Car cd player help?is it one of those which the front comes off so no one can steal it? if so there should be a small hole on the players that you do not remove and you need a sharp instrument like a pen to press it for a reset. if it isnt like mine, you need to contact a firm who puts cd players in cars and they will advise you.
